Text Chat Overlay for Video Communication
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
During real-time video communications, users with mobile devices or small screens face challenges in receiving and displaying text-based messages due to limited screen space, which can interrupt the video chat experience.
Innovation Solution
A method and system that allow text-based messages to be overlaid onto the video data displayed on a computing device during real-time video communication, enabling users to receive and interact with text messages without interrupting the video chat, using a touch-sensitive display and switching between video and text modes.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If text-based messages are displayed separately from video data on mobile devices, then text messages can be received during video chat, but the limited screen space prevents simultaneous display of both video and text
Solution Approach 1:
The patent combines text message display with video data display by overlaying text messages directly onto the video feed. This merging allows both video content and text messages to occupy the same screen space simultaneously, resolving the contradiction between receiving text messages and maintaining adequate video display area on mobile devices with limited screen real estate.
2Ease of operation
If text messages are displayed in a separate window or panel, then text communication is enabled, but the video chat experience is interrupted or degraded
Solution Approach 1:
By merging text message display with video data in an overlay format, the system enables text message interaction without creating separate windows or panels that would interrupt the video chat. The text messages appear as overlays on top of the video feed, allowing users to interact with text messages while maintaining continuous, uninterrupted video communication.
3Illumination intensity
If the screen is dedicated to video display, then video quality is maintained, but text messages cannot be displayed during video chat
Solution Approach 1:
The patent utilizes the z-dimension (depth layering) by overlaying text messages on top of video data. This dimensional approach allows text messages to be displayed in a separate visual layer above the video feed, enabling text message visibility without reducing the video display area or compromising video quality. The text messages occupy a different spatial dimension (overlay layer) rather than competing for the same two-dimensional screen space.

AI summary
In general, this disclosure describes techniques for overlaying information related to a text message onto a video. In one example, a method includes receiving communication data at a first computing device that is sent from a second computing device while the first and second computing devices are engaged in a real-time video communication, wherein the communication data comprises video data. The method also includes displaying the video data on a display of the first computing device and receiving a text-based message at the first computing device that is sent from the second computing device during the real-time video communication. The method further includes overlaying information related to the text-based message onto the video data displayed on the display of the first computing device.
